Metabolite Identification
Common NameLanosterin
DescriptionLanosterin, also known as botalan base 138 or lanosterol, belongs to the class of organic compounds known as triterpenoids. These are terpene molecules containing six isoprene units. Thus, lanosterin is considered to be a sterol lipid molecule. Lanosterin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.

Enzymes

Enzyme Details
1. Lanosterol 14-alpha demethylase
General function:
Secondary metabolites biosynthesis, transport and catabolism
Specific function:
A cytochrome P450 monooxygenase involved in sterol biosynthesis. Catalyzes 14-alpha demethylation of lanosterol and 24,25-dihydrolanosterol likely through sequential oxidative conversion of 14-alpha methyl group to hydroxymethyl, then to carboxylaldehyde, followed by the formation of the delta 14,15 double bond in the sterol core and concomitant release of formic acid. Mechanistically, uses molecular oxygen inserting one oxygen atom into a substrate, and reducing the second into a water molecule, with two electrons provided by NADPH via cytochrome P450 reductase (CPR; NADPH-ferrihemoprotein reductase).
Gene Name:
CYP51A1
Uniprot ID:
Q4PJW3
Molecular weight:
56596.0
Reactions
Lanosterin + 3 Oxygen + 3 NADPH → 4,4-Dimethylcholesta-8,14,24-trienol + Formic acid +3 NADP +4 Waterdetails
Enzyme Details
2. Lanosterol synthase
General function:
Translation, ribosomal structure and biogenesis
Specific function:
Catalyzes the cyclization of (S)-2,3 oxidosqualene to lanosterol, a reaction that forms the sterol nucleus. Through the production of lanosterol may regulate lens protein aggregation and increase transparency.
